■本研究旨在阐明微创非体外循环冠状动脉旁路移植术(mini-CABG)中隐静脉移植物(SVG)的良好流入部位,升主动脉之间,胸廓内动脉(ITAs)和左腋窝动脉(LAA)。
■这项回顾性研究包括2014年1月至2023年7月在我们中心接受Mini-CABG的126例患者。根据SVG流入部位将患者分为三组进行通畅性比较:主动脉组(n=56),LAA组(n=23),和ITA组(n=47)。
■有84名男性,平均年龄65.9±7.0岁。组间术前特点无显著差异。平均手术时间分别为254.6±72.2、213.7±57.6和253.0±81.2分钟,主动脉远端吻合口平均为2.9±0.9,2.4±0.7和2.9±1.1,分别为ITA组和LAA组。在重症监护病房的日子,住院,两组间主要并发症无差异.SVG的早期通畅性在各组之间没有显着差异:主动脉组为93.0%,ITA组98.0%,和100%在左心耳组。平均随访期为136.7±295.7天,随访冠状动脉CTA显示18例SVG闭塞(主动脉组n=8,ITA组n=5,LAA组n=5)。SVG通畅率的Kaplan-Meier曲线在三组之间没有显示任何显着差异。
■升主动脉,ITA,左心耳作为可靠的流入点,在小型CABG中结果相似。
UNASSIGNED: This study aims to clarify the good inflow site for saphenous vein grafts (SVG) in minimally invasive off-pump coronary artery bypass grafting (mini-CABG), between the ascending aorta, the internal thoracic arteries (ITAs) and the left axillary artery (LAA).
UNASSIGNED: This retrospective study included 126 patients who underwent Mini-CABG at our center between January 2014 and July 2023. Patients were divided into three groups according to the SVG inflow site for patency comparison: Aorta group (n = 56), LAA group (n = 23), and ITA group (n = 47).
UNASSIGNED: There were 84 males, with mean age of 65.9 ± 7.0 years. There were no significant differences in preoperative characteristics between groups. Mean operation times were 254.6 ± 72.2, 213.7 ± 57.6, and 253.0 ± 81.2 min, and the average numbers of distal anastomoses were 2.9 ± 0.9, 2.4 ± 0.7 and 2.9 ± 1.1 in the Aorta, ITA and LAA groups respectively. Days in intensive care, hospital stay, and major complications did not differ between the groups. Early patency of SVG did not significantly differ among groups: 93.0% in the Aorta group, 98.0% in the ITA group, and 100% in the LAA group. Mean follow-up period was 136.7 ± 295.7 days, and follow-up coronary CTA revealed 18 SVG occlusions (Aorta group n = 8, ITA group n = 5, LAA group n = 5). The Kaplan-Meier curve for SVG patency rates did not show any significant differences among the three groups.
UNASSIGNED: The ascending aorta, the ITAs, and the LAA serve as reliable inflow sites with similar results in mini-CABG.
